5G Testing

5G Test & Measurement Scenarios and Testing Solutions

5G Requirements

There are several projects and groups working worldwide to define 5G needs, technology requirements, user requirements, and other views on what 5G should be.

  • 5G ECOSYSTEM - The mobile network operators have built up an ecosystem community called Next Generation Mobile Networks (NGMN) which is creating a requirements document from the perspective of wireless network operators.
  • UNDERSTAND INDUSTRY NEEDS - NGMN had previously agreed requirements for 4G networks, and selected LTE as a preferred technology. The NGMN is an operator led forum, but with participation from the equipment/network vendors and supply chain, to try and align the industry needs.
  • EMERGING IoT NEEDS: Machine to machine (M2M) communication has a significant role to play in emerging internet of things (IoT) paradigm in years and decades to come. The emerging IoT-5G scenario extends sensor based IoT capabilities to robots, actuators and drones for distributed coordination and low-latency reliable execution of tasks at hand.  
  • TECHNICAL CHALLENGES - There are several key challenges to be met with future 5G networks, looking at the performance needs of future networks and identifying affordable technologies which may be developed to support these.

It is estimated that in year 2020, 20 to 40 billion devices will be connected to the Internet as part of the Internet of Things. A critical bottleneck for realizing the efficient IoT is the pressure it puts on the existing communication infrastructures, requiring transfer of enormous data volumes. 

5G Test and Measurement Challenges

5G channel model should support :

Wide range propagation scenarios and diverse network topologies. ( Network topology should not support only cellular networks but also communications of D2D , M2M and V2V )

● Higher communications frequencies and larger bandwidth. 5G may operate in frequency range from 350 Mhz to 100 Ghz.

● Massive MIMO . Planar wavefront assumption for conventional MIMO channels is no longer applicable and should be replaced by spherical wavefront assumption.

● Spatial consistency and dual mobility . 5G channel model should support spatial consistency.

● High mobility. With co-existence and density increase of links , and with application of D2D/ V2V , to support spatial consistency become especially important for wireless channel models.

Realness

In the 5G testing & evaluation, the requirement for realness is reflected in 5G wireless channel model, verification methods , user experience and other aspects.
From the point of network topology, various link types in 5G will co-exist in a same region, extending from traditional macrocell and microcell to picocell , femtocell and support V2V, M2M network architecture.

Comprehensiveness

Demand for testing & evaluating comprehensiveness (such as Transmission, Network & User experience indicators)  mainly involves two aspects :
● It lies in the comprehensive support for the evaluation of 5G performance indicators.
● It lies in the comprehensive support for the diversification of candidate technologies.

Rapidity

In order to meet the KPI’s in 5G, the computing performance of the simulation system must grow by more than 1000 times before meeting the requirements of the timely evaluation of simulation task.
With such rapid growth in computational performance , a systematic and brand new design & realization are needed in simulation system’s hardware platform , software platform and simulation application.

Flexibility

● Affected by flexible network architecture, network resource virtualization management , parallel computing needs & other factors, simulation & validation system needs to have enough flexibility.
● Architecture design , module design and interface design have the characteristics of coupling , modularization , interface expansion , easy integration and so on.
